On Saturday night I was laying in my bathtub (Been trying to take hot baths to help me relax) and I noticed my entire abdomen was bouncing, I immediately thought it was a muscle twitch I tried not to give it much attention thought it would go away. I later noticed that night when I was laying in my bed. Then again yesterday. I figured out its not a twitch it's my heart beat. I calmed down until I decided to google heart beat in your stomach. Uggggh! Abdominal aortic aneurysm came up. Its sutttle, I can't feel it, only see it. Its constant so I'm 100% sure it's my heart beat. I wonder if it's always been there and never noticed before. Its like my diaphragm is beating and its causing my entire torso so lightly bounce like a heartbeat. If I place my phone on my upper stomach it lightly bounces up and down with my heart beat. Its freaking me out!!!
